/* ───────────────────────────────────────────────────────────────────────────
HELIX paper layer — scientific styling ON TOP OF helix-artifact.css.
Use in an artifact:
Structure (see TEMPLATE.html for the full skeleton):
header.paper-head — eyebrow · title · byline (team/date/version/status)
.abstract — one-paragraph summary + .key results
section.sec — automatically numbered chapters (h2)
figure.fig — figure with an automatically numbered caption
figure.tab — table with an automatically numbered caption
.assumption — explicitly marked assumption (audit trail)
section.sources — numbered source list; inline
.provenance — data vintage · method · code · reproducibility
CLASS NAMES ARE ENGLISH; the Dutch names of the first generation
(.aanname, .aanname-blok, .formule, .symbolen, section.bronnen,
.verantwoording, .abstract .kern, .status.concept|gereviewd|definitief) keep
working as aliases — existing artifacts must not need a rewrite. New
artifacts use the English names (see TEMPLATE.html).
AUTOMATIC LABELS follow : "Abstract / Figure / Table" for
lang="en", "Samenvatting / Figuur / Tabel" for anything else, so Dutch
artifacts keep their Dutch labels.
